How to make industrial automation system open?

In the era of the Internet of everything, it is necessary to promote the application of the industrial Internet, realize intelligent manufacturing, and establish a fully open and interoperable automation system that is the way out of industrial automation. In order to truly achieve the integration of IT and OT, the primary goal is to fill this gap, completely innovate themselves, and integrate into the open automation ecosystem.

Under the strong pull of market demand, industrial automation will inevitably change by leaps and bounds, gradually moving from closed to open. The connotation of open automation ecology is the standardization and open resource sharing of the automation industry, through the development of various standards for industrial automation providers to create good compatibility and cooperation, but also for manufacturing enterprises to bring more flexibility and cost advantages.

To achieve the openness of the industrial control system, we must first break down barriers and establish industry standards in the field of automation.

For example, the IEC61131-3 international standard of the PLC programming language is a global standard in the field of industrial control developed by the IEC International Electrotechnical Commission. IEC61131 has been used in industrial control applications for a long time and is familiar to most programming engineers. But IEC61131 standard is suitable for single machine operation, to achieve the design of distributed control not only workload, but also need a lot of manual modification, efficiency is not high.

Another standard, IEC 61499, is an executable system-level modeling language based on event-triggered functional blocks, which provides a standardized encapsulation method for logical code. The IEC 61499 standard changes the status of control hardware and software have been tightly tied together for many years. It not only solves the problem of portability, configurability and interoperability between devices from different vendors, but also solves the problem of software and hardware independence.
